ÆNUS, Ænos, or Ænum, in Ancient Geography, a town of Thrace, situated on the eastmost mouth of the Hebrus, which has two mouths; and said to be built by the Cumæans. It was a free town, in which stood the tomb of Polydorus, (Pliny); Ænius is the epithet. Here the brother of Cato Uticensis died, and was honoured with a monument of marble in the forum of the Ænii, (Plutarch); called Ænei, (Stephanus). Livy says that the town was otherwise called Abynthus. Now Eno.
